Technical Specifications
| Item | Description | Details |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors if polarity is not fixed or determined. Not suitable for AC applications. | DC electrolytic capacitors are polarized. Use bipolar capacitors for uncertain polarity. Not for AC. |
| Bipolar Capacitors | Suitable for pulse circuits and polarity reverse circuits. Not applicable for pure AC or high ripple current circuits. | For pulse and polarity reverse circuits only. Not for pure AC or high ripple. |
| Voltage Application | Do not exceed the rated voltage. Recommended working voltage is 70-80% of rated voltage for extended lifespan. Exceeding rated voltage increases leakage current and may cause damage. | Working voltage: 70-80% of rated voltage. Do not exceed rated voltage. |
| Ripple Current | Do not allow excessive ripple current, which can cause overheating, reduced capacitance, and damage. Ripple current should generally not exceed 80% of the rated value. | Ripple current should not exceed 80% of rated value. |
| Fast Charge/Discharge Circuits | Use specially designed capacitors for circuits with frequent charge and discharge cycles to prevent damage, capacitance decrease, and heat rise. | Use specialized capacitors for high-frequency charge/discharge circuits. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures ensure longer life. | Lower operating temperatures prolong capacitor life. |
| Temperature and Life Relationship | Capacitor life is related to operating temperature. Reducing temperature by 10 can double the lifespan at rated temperature. Formula provided for calculation. | Life approximately doubles for every 10 decrease in temperature. |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature. | Capacitance decreases and tg increases with higher frequencies. |
| Long-Term Storage | Capacitors stored for extended periods may experience increased leakage current and reduced withstand voltage. Before use, apply rated DC voltage gradually. | Treat with rated DC voltage before use after long storage. |
| Case Insulation | The capacitor case is connected to the cathode terminal via the electrolyte. If case insulation is required, implement insulation measures at the mounting point. | Capacitor case is not insulated from the cathode. Implement insulation at mounting if required. |
| Terminal/Lead Force | Do not apply excessive force to terminals or leads to prevent breakage, separation, or internal connection failure. | Avoid excessive force on terminals and leads. |
| Lead Bending | When bending leads for horizontal mounting, maintain a 2mm safe distance from the capacitor body to prevent internal structural damage. | Maintain 2mm safe spacing when bending leads for horizontal mounting. |
| Circuit Board Cleaning | Use recommended solvents (Methanol, Isopropanol, Ethanol, etc.) for cleaning circuit boards. Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect the capacitor's sleeve, marking, and sealing materials. | Recommended cleaning solvents: Methanol, Isopropanol, Ethanol, etc. Avoid halogenated solvents. |
| Soldering | Maintain distance between soldering iron and the plastic sleeve. Recommended solder bath temperature is within 260 for no more than 10 seconds to prevent damage. | Soldering: Max 260 for 10 seconds. Keep iron away from plastic sleeve. |
| Hole Layout on PCB | Ensure mounting hole spacing matches lead spacing to avoid stress on leads, short circuits, or circuit damage. Consider hole layout to prevent solder splashing onto the capacitor sleeve. | Ensure hole spacing matches lead spacing. Consider hole layout to prevent solder splash. |
